Actress Reese Witherspoon has not ruled out having more children with her husband, Jim Toth.

At the Hollywood premiere of her new action packed comedy film, "This Means War" on Wednesday, Witherspoon, who turns 37 in March, told Us Weekly that she loves the idea of having more children.

"I would love that!" Witherspoon, said. The "Legally Blonde" actress married Toth, a talent agent, last March. The pair reportedly began dating in early 2010.

Toth is already the stepfather of Witherspoon's two children, Ava, 12, and Deacon, 8, with ex husband, actor Ryan Phillippe.

"I'm really happy," Witherspoon told Us Weekly. "I feel really good and I'm at a really good place in my life."

But the actress wasn't always in such a good place romantically. Witherspoon separated from Phillippe after seven years of marriage. The couple met in 1997, when Reese was just 21 years old, and were engaged one year later. They tied the knot in 1999.

"I was hard on myself when I got divorced. And until I got remarried, I don't think I realized how stressed I was," the Academy Award winning actress said in the October 2011 issue of Marie Claire. "I feel so much relief. I don't think I recognized how anxious I was about being a single parent. It was really, really stressful. It's not easy on anybody."

Although Witherspoon and Phillippe still maintain joint custody of their two children, the actress said she was "blessed" to find a man like Toth, who is accepting of her young children.

"You know, somebody close to me once said, 'Oh, no man will ever accept your children.' And I just thought it was the most horrifying thing someone has ever said to me in my entire life," she told Marie Claire. "I was determined to find somebody who would make that not true. And I got lucky. I did. I got very lucky, and he's wonderful. And so wonderful with the children. I'm very blessed."

So with two children, possibly more on the way and nearing the 40-year mark, how does Witherspoon, who wore a form fitting black bustier to the premiere, stay in such great shape?

"I work out all the time anyway just to stay healthy," she told Us Weekly. "I don't believe in crash dieting or anything like that."

Her advice to other working mothers: "Every working mother has to balance work and the children and just enjoy it, because it all goes very fast!"
